Antique RS Prussia six paneled porcelain bowl

This fully unmarked pocelain was bought to Mauricio Adari a year ago when we traveled to Rafaela, Santa Fe. There he has a huge shop and we bought two oils pictures, two Kralik vases and two unmarked porcelains a cup and this cute and very old bowl. I believe it is an unmarked early RS Prussia because of the high quality of the modeled reliefs in the panels (first and second pictures) the whitenes and gloss of the porcelain. The transfered angels and flowers are all different one from the other. If some one has something similara please post it.
